I believe in the right to open carry. That said, the actual practice is not a great idea without a high level retention holster. You cannot see behind you, even if you are on high alert. Perhaps one day there will be enough carriers that the danger is negated, until then, it's a good idea to be concealed in 90% of cases. You can defend OC in any number of ways, but there is an inherit danger with relatively low numbers of the population carrying firearms. In most instances, statistically, there will be no one to back you up. That's a real problem for me.
